What is the Difference Between Ammonia and Bleach?

🆚 Go to Comparative Table 🆚

Ammonia and bleach are both effective cleaners, but they have different properties and uses. Here are the key differences between the two:

  1. Composition: Ammonia, also known as ammonium hydroxide, is a compound made up of one nitrogen atom and three hydrogen atoms (NH3). Bleach is made from water, caustic soda, and chlorine.
  2. Strength: Ammonia is considered a weak base, while bleach is a strong oxidizing agent.
  3. Disinfectant Qualities: Bleach is a more powerful disinfectant than ammonia, killing bacteria and viruses on contact. Ammonia, on the other hand, does not have disinfectant properties and is primarily used for cleaning purposes.
  4. Surface Compatibility: Ammonia is better suited for cleaning hard surfaces like tiles, glass, and jewelry, while bleach is generally used on fabrics, especially white clothes, and for washing dishes and kitchen utensils.
  5. Color Change: Bleach can lighten the color of surfaces, making it unsuitable for colored fabrics. Ammonia does not cause color change and can clean surfaces without affecting their appearance.

It is important not to mix ammonia and bleach, as the combination creates a toxic and potentially deadly gas. Always use these cleaners separately and follow the manufacturer's instructions for safe and effective use.

Comparative Table: Ammonia vs Bleach

Here is a table comparing the differences between ammonia and bleach:

Characteristic Ammonia Bleach (Sodium Hypochlorite)
Composition Nitrogen and hydrogen Sodium hypochlorite, sodium hydroxide, hydrogen peroxide, and calcium hypochlorite (trace amounts)
pH Alkaline, around pH 11.6 Alkaline, around pH 12.3
Common Uses Cleaning surfaces, removing stains, and brightening fabrics Disinfecting, whitening, and removing stains
Strength Weak base Strong base
Toxicity Toxic, may cause irritation and respiratory issues Toxic, may cause irritation and respiratory issues
Mixing Hazards Mixing with bleach can produce toxic gas chloramine Mixing with ammonia can produce toxic gas chloramine, and with peroxide-based bleach, a violent reaction

Ammonia and bleach are both used as cleaning agents, but they serve different purposes and have different properties. Ammonia is primarily used for cleaning surfaces and fabrics, while bleach is used for disinfecting and whitening. Bleach is a stronger base than ammonia. Mixing ammonia and bleach can produce a highly toxic gas called chloramine, which can be fatal if inhaled. It is essential to use these cleaning agents separately and with proper precautions.
